A Study of TAK-951 to Stop Adults Getting Nausea and Vomiting After Planned Surgery
United States89 participantsStarted 2020-10-20
Plain-language summary
Some adults are at a higher risk of feeling sick (nausea) or being sick (vomiting) after they have surgery. In this study, these adults will have planned surgery. The main aim of this study is to learn if TAK-951 stops these adults from getting nausea or vomiting after surgery. This will be compared with another medicine called ondansetron. Another aim is to check for side effects from the study medicines.
Before surgery, the study doctor will check who can take part in this study. Those who can take part will be picked for either Treatment Group A or Treatment Group B by chance.
* Treatment Group A: Just before surgery, participants will receive a placebo slowly through a vein (infusion). Just before the end of the surgery, they will receive TAK-951 as an injection under the skin.
* Treatment Group B: Just before surgery, participants will receive ondansetron slowly through a vein (infusion). Just before the end of the surgery, they will receive a placebo as an injection under the skin. In this study, a placebo will look like TAK-951 but will not have any medicine in it.
Participants will not know which study medicines they received, or in which order, nor will their study doctors or surgeons. This is to help make sure the results are more reliable.
Participants will stay in the hospital for 24 hours after their surgery so that the study doctors can check for nausea and vomiting. The study doctors will also check for side effects from the study medicines.
Participants will visit the hospital for a check-up 14 days later.

Inclusion criteria
ā. Participants undergoing elective surgery under general anesthesia, expected to last for at least 1 hour from induction of anesthesia to wound closure.
ā. Participants are expected to require or have agreed to stay, at least 1 overnight in the hospital.
ā. Participants American Society of Anesthesiologists (ASA) physical status is ASA I-III.
ā. Participants with 3 or more Apfel risk factors defined as:
ā. Female sex.
ā. Nonsmoking status (never smoked or stopped smoking ā„12 months ago).
ā. History of PONV or motion sickness.
ā. Planned use of postoperative opioid analgesics.
Exclusion criteria
ā. Participants who are expected to remain intubated post-anesthesia.
ā. Participants who experience nausea or vomiting within 24 hours before surgery or are diagnosed with gastroparesis, cyclic vomiting syndrome, or other condition associated with acute or chronic nausea and vomiting.
What they're measuring
1
Percentage of Participants With Complete Response in the Immediate Postoperative Period
ā. Participants who have received, or are expected to receive, any excluded drug preoperatively within 24 hours before induction, during surgery, or within 24 hours after surgery.
ā. Participants scheduled to receive neuraxial anesthesia (e.g., epidural, spinal, or caudal anesthesia), regional blocks, or total IV anesthesia, and/or planned to receive different drugs for premedication, induction, maintenance, or reversal of anesthesia than those specified in the protocol.
ā. Participants who have an allergy or contraindication to the recommended and available rescue therapy for the treatment of PONV.
ā. Circumstance that, in the investigator's opinion, make participation in this clinical study inappropriate.
ā. Participants found at the screening to have a QT interval with Fridericia correction method (QTcF) ā„450 msec or other factors that increase the risk of QT prolongation or arrhythmic events. Assessments showing bundle branch block and a prolonged QTcF should be discussed with the study monitor and the sponsor for potential inclusion.
ā. Participants who have a direct family history of premature sudden death or channelopathy, personal history of Brugada syndrome (right bundle branch block pattern with ST elevation in leads V1-V3), long QT, short QT, arrhythmogenic right ventricular dysplasia, hypertrophic cardiomyopathy or catecholaminergic polymorphic ventricular tachycardia (VT).
